WILLIAM GIFFORD MOWRY, QF GREENWIOH, NEW YORK.

VEHICLE-SPRING.

SPECIFICATION forming part of Letters Patent No. 290,461, dated December 18, 1883..

Application filed April 24, 1883. (No model.)

To all whom it may concern Be it known that I, WM. G. MOWRY, a citizen ofthe United States, residing at Greenwich, in the county of Washington and State of New York, have invented certain new and useful Improvements in Vehicles, of which the following is a specification, reference being had therein to the accompanying drawings.

'My invention relates to light side-bar wagons, and has for its object the combining with the side bars two wooden truss-springs, in such manner that they will act similarly to the ordinarybuckboard, but in support of the side bars and body, as will be hereinafter more fully set forth.

In the accompanying drawings,making part of this specification, Figure 1 is a perspective of the side bars and springs with their connections, and Fig. 2 is a perspective of the end of one of the truss-springs.

In'the figures, A A represent the side bars of a wagon, which may be made in any of the well-known and usual ways.

DD D represent three cross-bars, made of any suitable material, which are bolted to the side bars at suitable distances apart, as shown in Fig. 1.

B 13 represent two truss-springs, which are made of wood, with a portion of their under sides, near their ends, preferably provided with metal plates d, to prevent wear of the wood. These springs B B are bolted at their centers to the under side of the center crossupon the upper sides of the two outer bars, D D. These springs B B are located on each side of the frame and near the side bars, and of course may be made of any suitable strength and thickness.

The body of the wagon maybe made to rest upon any suitable risers or brackets, or upon the side bars, or upon the center bar or bars, with or without brackets, as may be desirable. The auxiliary or truss springs, it will readily be seen, act in conjunction with the side bars, and in performing the functions of a buckboard a light and elastic frame is formed for the body, and one not liable to sag on either side by reason of there being more weight upon one side than upon the other.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

" In a side-bar wagon, the side bars, A A,

- connected together on their under sides by the cross-bars D D D, in combination with an auxiliary spring to each side bar, the springs being bolted to the under side of the middle bar, D, and their ends playing freely upon the outer bars, D D, substantially as and for the purpose described.

In testimony whereof I affix my signature in presence of two witnesses.

WILLIAM GIFFORD MOWRY.
